Preheat oven 200°F. Place tofu on a plate lined with several layers of paper towels; cover with additional paper towels and a second plate. Place a weight on top. Let stand 30 minutes. Coat tofu with cooking spray. Place half of the tofu in single layer in air fryer basket, and cook at 375°F until crispy and golden brown, about 15 minutes, turning tofu cubes over halfway through cooking. Keep warm in preheated oven while cooking remaining tofu. Meanwhile, whisk together orange juice, soy sauce, honey, sesame oil, rice vinegar, and cornstarch in a small saucepan over high. Bring to a boil, whisking constantly, until sauce thickens, 2 to 3 minutes. Remove from heat; set aside. Prepare rice according to package directions. Stir in salt. Toss tofu with soy sauce mixture. Divide rice among 4 bowls; top with tofu. Sprinkle with scallions and sesame seeds.
